Is there any such thing as an alkaline battery that does not leak
with age?

Yes. *

However, I have no experience with these. *I've been wrapping my
flashlight batteries in cellophane wrap for years. *I have had leaks,
but little damage.

I just had my second episode of Mallory Duracells gooping up a
flashlight.

How old were the batteries?

If the answer is "no", can anybody venture a proactive
replacement interval for size "C" cells?

5 years would be my guess. *The ideal self discharge rate of about 2%
for alkalines should leave you with a 90% charge after 5 years.
However, getting the battery hot, as in your vehicle (or bicycle),
will rapidly decrease the self discharge rate. *When the battery gets
nearly dead (at about 25% capacity), it starts to belch hydrogen,
which is the major cause of leakage.

Maxells used to be available at the local Fleet Farm. They lasted,
didn't leak, and were cheap. The packaging was white with black and
gold.
They were made in Japan and now China.
